Rosie, having gone through something vaguely similar for the past year, and all the yucky endoscopy/colonoscopy stuff, I would just advise you to keep on your doctor and keep asking questions until you get answers. I was a bit too laid back in the beginning ("oh, they'll get back to me eventually") and felt miserable for longer than I needed to, instead of saying "What other things can we be doing while we wait for those biopsy results? Blood work? Other testing?" Good luck to both of you...a clean endoscopy is a good thing!
